摘要

Flower initiation and development in 0900 Ziraat sweet cherry (Prunus avium) and Glohaven peach (Prunus persica) were examined using scanning electron microscopy. The objectives were to determine the timing of floral developmental stages and to achieve a better understanding of the morphological changes during flower formation at the apex of axillary buds of sweet cherry and peach cultivars. In cherry, bud samples were taken every 10 days from 26 June to 24 August and stored in formalin, 70% ethanol, and acetic acid solution (10:50:5, by volume). In peach, bud samples were collected every 10 days from 28 June to 16 September and stored in the same solution. In cherry, on 5 July, 85 days after anthesis (DAA), a swelling of the apex signified the initial change from the vegetative to the reproductive stage. Flower primordia differentiated in the axils of bracts on 15 July. Sepal primordia were evident on 15 July, 15 weeks after anthesis, and petal primordia had formed by 4 August. Concentric rings of stamen primordia differentiated between 4 and 24 August, followed by the pistil. These organs of the flower attained their normal forms by the end of August. In peach, on 8 July, 109 DAA, a flattened apex signified the initial change from the vegetative to the reproductive stage. After this stage, floral primordia developed in the order of sepal, petal, stamen, and carpel. Sepal primordia were evident on 17 August, 149 DAA, petal primordia were evident on 27 August, 159 DAA, and rings of stamen primordia had formed by 16 September, followed by the carpel. These organs of the flower attained their normal forms by the end of September.
